Abstract: An IC includes logic cells, selected from a standard cell library, and fill cells, configured for compatibility with the standard logic cells. The fill cells contain structures configured to obtain in-line data via non-contact electrical measurements (“NCEM”). The IC includes such NCEM-enabled fill cells configured to enable detection and/or measurement of a variety of open-circuit and short-circuit failure modes, including at least one via-open-related failure mode, one AACNT-short-related failure mode, one TS-short-related failure mode, and one metal-short-related failure mode.

Abstract: Electromigration can be reduced in a copper-based metallization of an integrated circuit that includes a first copper-containing via that electrically connects an underlying conductive line and an overlying copper-containing line through an intervening insulating layer. Electromigration can be reduced by forming at least a second copper-containing via that electrically connects the underlying conductive line and the overlying copper-containing line through the intervening insulating layer, in parallel with the first copper-containing via. Multi-vias can provide redundancy to reduce early failure statistics. Moreover, since current is distributed among the vias, the electromigration driving force can be reduced and local Joule heating, in voids at the via interface, also may be reduced. Accordingly, even if via voids are formed, the structure may not fail by catastrophic thermal runaway due to Joule heating.

Abstract: A semiconductor device comprising a substrate, a conductor and an insulating film provided on the surface of the substrate, part of the surface of the substrate being electrically connected with the conductor through a contact hole made in the insulating film, wherein a barrier layer present between part of the surface of the substrate and the conductor is provided only on the bottom of the contact hole, and the barrier layer provided on the bottom comprises amorphous titanium silicon nitride. This can provide a structure that has a barrier layer with a low contact resistance, enables formation of a conductor film of good quality on the barrier layer, and can attain a good electrical conduction even at fine contact holes.
